Which I should I use? I have both, and I'm building up a bike. XTR is in decent shape, XT is like new. Thanks

Use the old first, wear it out, and then install the new. OR Use the new now and pack the old for a trailside swap if/when you waste the new (just don't pack the new derailleur for trailside swaps).

Assuming that the drivetrain capacity requirements have all been worked out, then my process of selection goes something like this:

1. Matching hierachy - if the shifters are XTR then use the XTR RD. If the shifters are lower than XTR, then use either one with the following additional consideration:

2. Matching colours - use the RD that best matches the colour or styling of the FD, chainset, or other components on the frame.

3. If intended for a weight weenie build, then choose XTR.

Functionally, the XTR will be smoother or mushier as compared to the XT depending on your point of view. The RD-M761 has a stronger spring as compared to the RD-M952 (in my opinion), so will plink more firmly into gear. The RD-M952 will seem to glide into gear.

The choice is yours...

I would keep the un-used derailluer for a spare.
What are you going to get for a used derailluer on FleaBay? Not much.
Not worth the effort to me.
My luck would be, as soon as that derailleur shipped out, after selling for $10, I would frag one on the trail and have to pay full price for a new one.:rolleyes:

Probably about $35 for the XT.
